1. An object detection device, comprising:
a first sensor configured to output a radio frequency (RF) signal, to receive a reflected RF signal reflected from an object, and to obtain a first measurement value for the object based on a received reflected RF signal;
a second sensor configured to obtain a second measurement value for the object by sensing a physical characteristic from the object, the physical characteristic sensed by the second sensor being different from a characteristic of the object measured as the first measurement value obtained by the first sensor;
a calculation range selector configured to set a first reference range based on the second measurement value obtained by the second sensor, the first reference range representing a range of execution of a first calculation for detecting a position of the object using a first algorithm; and
an estimator configured to perform the first calculation only on the first reference range set by the calculation range selector based on the second measurement value obtained by the second sensor, using the first measurement value obtained by the first sensor, and to generate a first result value as a result of performing the first calculation, the first result value representing the position of the object.
